My first plan would also be to get out of town. But remember I said a
SHTF condition. Shotgun would be to unwieldy inside of a house. Cut
the barrel off and that's a problem with the law. AR15 packs plenty of
punch if you are using 65 or 75 gr ammo. Normal is 45 or 55 gr. Also
most AR15s shoot 5.56 which is harder hitting than 223. There's enough
dead Iraqs to prove the AR is a good enough weapon.
